Installation
CAUTION
•To prevent product damage, always disconnect
the power supply from the product before
performing installation.
IMPORTANT:
•
void application that keeps product operating
cycle excessively frequent.
•Meet the rotating direction of the actuator with the
damper rotating direction.
•Tighten the screws so that the actuator is securely
assembled with the damper.
•For the product installation, secure maintenance
clearance shown in Fig. 1.
Installation procedure
1) Fully close the damper shaft.
Figure 4. Damper shaft
2) Fully close the actuator Model MY6050A, and mount it
to the damper shaft. Finger-tighten the fastening nuts of
the shaft clamp to temporarily fix the actuator.

3) With the gear release button pressed , manually rotate
the shaft clamp until it is in the position shown in Fig. 6.
Then, insert the universal bracket into the slit of the
actuator and fix the bracket onto the damper with the two
M4 tapping screws.

4) Manually rotate the shaft clamp back to the fully closed
position with the gear release button pressed. At this
time, be sure to leave a clearance (approx. 1 mm)
between the shaft clamp and the rotation angle adjuster
(mechanical stopper). Using a wrench, tighten the
fastening nuts of the shaft clamp to completely fix the
actuator.

5) Attach the position indicator ring to the damper shaft so
that the tip of the damper blade and the pointer of the
indicator ring point to the same direction.
Adjust the rotation angle adjuster on the fully open side
depending on the damper rotating angle.
